Ground beef is not at all common in authentic Mexican cooking. When ground beef is used in Mexican cooking it is usually seasoned with onion and/or garlic, worcestershire sauce and salt. This would be in the case of meatballs or picadillo.
Authentic restaurants don't use ground beef, they use chopped beef which is usually seasoned with garlic, salt, pepper and maybe a little chili. Very simple so that you can still taste the tortilla.How is the ground beef seasoned in authentic Mexican restaurants?
